BLOW-OUT PATCH.

Application filed July 20, 1925. Serial No. 44,831.

This invention relates to an improvement in blow-out patches and aims to provide a blow-out patch adapted to co-act with the valve stem of an inner tube and hold the same in proper position on the tire, the present invention eliminating the use of any fastening means or securing devices liable to pinch the tire.

A. further object is to provide a blow-out patch of this character which may be constructed at comparatively slight expense from the old discarded shoes or casings of automobile tires and yet provides effective and reliable protection against blow-outs.

Other objects and advantages reside in'certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is a View in elevation showing how the blow-out patch is applied to the inner tube of the tire,

Figure 2 is a plan view of the blow-out patch laid out flat, and

Figure 3 is a detail perspective'view showing how the blow-out patch is wrapped around the inner tube and associated with the valve stem. 1

Referring to the drawing the numeral 1 designates generally a blow-out patch con structed in accordance with the present invention. The blow-out patch preferably consists of alternate layers of rubber and fabric permanently united by vulcanization and may be conveniently obtained from the shoe or casings of discarded automobile tires. In cutting the blow-out patch from an old casing the layer to be applied to the inner tube is the largest, as indicated at 2, the other layers being successively smaller and being designated at 3, 4 and 5.

The blow-out patch may be of any suitable shape but is preferably of rectangular or square form in plan. At diagonally opposite corners openings 6 are provided in the patch, the openings 6 being formed a slight distance from the corners so as to extend through at least several of the layers whereby the walls of the openings are strong and resist tearing.

In applying the device the valve stem 7 of the inner tube 8 is inserted through one of the openings 6. The patch is then extended around the inner tube and the other opening 6 is brought into alignment with the valve stem and the valve stem inserted therethrough. This brings the corners 9 of the patch in overlying relation and brings the remainder of the patch into snug engagement with the inner tube. The inner tube is then placed in the shoe or casing of the tire in such a manner as to position the patch in proper relation to the punctured or weakened portion. Then when the inner tube and casing are mounted on the wheel and the inner tube inflated, the blow-out patch will be firmly and securely held against displacement.

I claim:

1. A blow-out patch having opposed portions provided with openings adapted to receive the valve stem of an inner tube, where by the patch is held in position.

2. A blow-out patch having openings at diagonally opposite corners adapted to receive the valve stem of an inner tube w rereby the blow-out patch is held in position.

3. A blow-out patch of polygonal form having openings at diagonally opposite corners adapted to receive the valve stem of an inner tube whereby the blow-out patch is held in position.

4. In combination with an inner tube having a valve stem, a blow-out patch adapted to be wrapped around the inner tube and having portions provided with openings receiving the valve stem, said portions being arranged in overlapping relation on the portion of the inner tube around the valve stem, and the remainder of the patch snugly fitting around the inner tube.

5. A blow-out patch comprising alternate layers of rubber and fabric united by vulcanization and provided with openings adapted to receive the valve stem.

6. A blow-out patch adapted to be constructed from discarded tire casings and consisting of layers of successively decreasing size cut from the old tire casings said patch being of polygonal form and having openings at diagonally opposite corners adapted to receive the valve stem of an inner tube whereby to properly position the patch.
